  2. ENTRY UNLOCK MODE SWITCHING 
    NOTE:

    Because the key (for card type) does not have a wireless transmitter function, it cannot be used to change the entry unlock mode.

    1. Check that the power source mode is OFF and the LED on the key is not blinking. Press the lock switch and one of the other switches on the key at the same time for approximately 5 seconds while the key is in the detection area.

      Driver door unlock default setting:

      When the switches are pressed and held for 5 seconds, the entry door unlock mode changes to the mode that is not currently selected.

      NOTE:

      After pressing and holding the switches for 5 seconds, wait 5 seconds before performing the same procedure again.

      • Driver door unlock mode:

        When the driver door touch sensor is touched, only the driver door unlocks. When another touch sensor is touched, all doors unlock.

      • All door unlock mode:

        When any touch sensor is touched, all doors unlock.

    2. The certification ECU (smart key ECU assembly) receives this signal from the door control receiver assembly and changes the smart access system with push-button start to the entry unlock mode.
    3. The certification ECU (smart key ECU assembly) sounds the buzzers of the wireless door lock buzzer assembly and combination meter assembly (buzzer) to inform the user that the mode has been changed.
      Mode Wireless Door Lock Buzzer Assembly Combination Meter Assembly (Buzzer)
      Driver Door
      (Default)
      Sounds 3 times Sounds once
      All Doors
      (Customized)
      Sounds 2 times Sounds once

      HINT: 

      The procedure only changes the entry unlock mode of the smart access system with push-button start. It does not switch the unlocking of the wireless door lock control.

  3. ELECTRICAL KEY CANCEL 
    NOTE:

    Because the key (for card type) does not have a wireless transmitter function, it cannot be used to perform the key cancel operation.

    The electrical key cancel operation disables the following functions:

    • Entry Unlock/Lock
    • Entry Ignition
    • Entry Back Door Open
    • Electrical Key Lock-in Prevention
    • Warning
    • Memory Call
    1. The operation procedures are as follows:

      Precondition:

      Engine switch off, driver side door closed and unlocked.

      1. Push the unlock switch of the key once.
      2. Open the driver door within 5 seconds.
      3. Push the unlock switch of the key twice within 5 seconds.
      4. Close and open the driver door twice within 30 seconds.

        (Driver door: Close → Open → Close → Open)

      6. Close and open the driver door within 30 seconds.

        (Driver door: Close → Open)

        When electrical key cancel is activated, the wireless door lock buzzer sounds twice.

        To return to the original condition, perform the procedures again. When the original condition is returned, the wireless door lock buzzer sounds once.
